3. Date of data collection: Artifacts excavated from Angkor Borei, Cambodia in 1999-2000, Analyses of glass beads/objects by Laure Dussubieux completed 2001 and 2019; Analyses of glass beads by Alison Carter in 2013. 

4. Geographic location of data collection: Artifacts from Angkor Borei, Cambodia and Oc Eo, Vietnam.  Objects classified LD in Appendix C were analyzed by Laure Dussubieux at the Centre Ernest Babelon, IRAMAT, CNRS, Orléans, France. Objects classified LD19 in Appendix C were re-analyzed  in 2019 in the Elemental Analysis Facility at the Field Museum, Chicago. Objects classified AKC in Appendix C were analyzed in the Elemental Analysis Facility at the Field Museum, Chicago.

DATA & FILE OVERVIEW

1. File List: 
AngkorBoreiBeadDataset_GlassContext.tab: Detailed context information on glass beads recorded by Carter from the site of Angkor Borei, Cambodia.

AngkorBoreiBeadDataset_Stone.tab: Detailed context information on stone beads recorded by Carter from the site of Angkor Borei, Cambodia.
